Unfortunately, method #2 didn’t work on an iPhone 6s on iOS14.6 (latest available).
We created a new contact with the phone # “0000000000” and double-checked this contact is blocked and when we try to call from another cell phone with Caller ID off, it still rings with “No Caller ID”
We changed the name of the contact to “NO CALLER ID” and it notices it still comes up “No Caller ID” so this must be a string internal to the phone.
This explains why we can’t change the ringtone for this contact either.
Hey Chinarut, Thanks for dropping by. Well, that’s weird. This probably has to do with your phone. Did you try it with a different phone?
